Genes affected

SIPA1L1 (HGNC:20284): (signal induced proliferation associated 1 like 1) Predicted to enable GTPase activator activity; actin filament binding activity; and protein kinase binding activity. Predicted to be involved in several processes, including actin cytoskeleton organization; activation of GTPase activity; and regulation of postsynapse organization. Located in actin cytoskeleton and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.233 is higher than 0.05.
